Finally, we feed Eq. (REF ) and Eq. (REF ) to the MATLAB function gamultiobj to obtain three-dimensional Pareto fronts for \(\eta \) , \(v\) , and \(\Delta \sigma \) . The function gamultiobj uses genetic algorithms [1]} and numerical evaluations of Eq. (REF ) to find the combination of free parameters corresponding to the dominant configurations of \(\eta \) , \(v\) , and \(\Delta \sigma \) .
